So I have done a decent amount of drywalling recently and know of a few techniques that can be done when patching holes. I am curious if someone with much more drywall experience can help define a better method?
So far what I know as techniques are:
- Just using joint compound to fill the hole
- Sticking drywall tape or some other mesh across a hole and then placing joint compound on top of it
- Screwing the drywall directly to a stud or other 2x4 support behind it if one is exposed and available, tape around edges, joint compound on top.
- Installing an entire 4 x 8 sheet where both sides get plenty of screws, tape on edges, then joint compound on tape
- Installing a support behind, anchoring to it, tape, joint compound
So I would assume that:
- Technique 1 can be used for very small holes. Probably 1/2 inch or smaller?
- Technique 2 can be used for slightly larger holes than technique 1 but at what size does this seem to be ineffective?
- Technique 3 and 4 are always a good choice when available but they are not always available as sometimes the hole is not big enough to do these. Is it better to make the hole bigger so one of these can be used?
- I have used technique 5 mostly for ceilings where any installed drywall that is too large will simply fall off.
So my question is basically when should you use each technique? Am I missing any or should any I listed not be used?
